Study Notes

RISC Architecture

SPARC and MIPS processors are the first generation processors of RISC architecture.

80/20 Rule

80% of instructions are generated and only 20% of the instruction set is executed.
This leads to the formation of RISC (Reduced Instruction Set Computing) which simplifies instructions to increase processor performance.

Complex Architecture

SPARC has RISC architecture which has a simple instruction set.
MC68020, MC68030, and 8086 have CISC (Complex Instruction Set Computing) architecture which is more complex.

RISC Definition

IBM defined RISC architecture in the 1970s.

Single Cycle Execution

MIPS R2000 executes its instructions in a single clock cycle.
It synthesizes complex operations from the same reduced instruction set.

Memory Access in RISC

Data is loaded into a register and manipulated, then written out to the main memory.
This is done using load and store instructions.

Harvard Architecture

RAM (Random Access Memory) has a Harvard architecture.
When the board is powered up, the reset vector from the EPROM makes the initialisation of the board and is transferred to the RAM from the EPROM.

Platform-Based Design

It allows the reuse of software and hardware components.
It helps in coping with the increasing complexity in the design of embedded systems.

Software/Hardware Codesign

It is a design that considers both hardware and software during the design process.
It helps in finding the right combination of hardware and software for an efficient product.

API

API stands for Application Programming Interface.
It helps in extending the platform towards software applications.

Task-Level Concurrency Management

It is concerned with identifying the tasks at the final embedded systems.
It helps in identifying the tasks that need to be present in the final embedded systems.

High-Level Transformation

It is responsible for high optimizing transformations.
It can interchange loops and transform floating point arithmetic to fixed point arithmetic.

Hardware/Software Partitioning

It is in charge of mapping operations to hardware or software.
It helps in deciding whether to implement an operation in hardware or software.

Scheduling

It is performed in several contexts.
It should be approximated with other design activities like compilation, hardware/software partitioning, and task-level concurrency management.
